<P>I just recently upgraded to FIOS TV One which includes the VMS4100 media server and 3 clients.&nbsp; I have an LG 70UH6350 TV (4K, UHD, HDR Pro) and a Vizio Soundbar SB4551 (5.1).&nbsp; Prior to the FIOS upgrade I had the older Motorola&nbsp; 7232-P2 DVR&nbsp; and several Motorola 7100 HD STB's. I never had the previous VMS 1100.&nbsp; On my new VMS4100 I have noticed significant A/V sync issues.&nbsp; I never had any A/V sync issues with the 7232 DVR.&nbsp; The Vizio soundbar and the VMS4100 are both connected via HDMI with ARC - CEC enabled.&nbsp; I have read that this was an issue for the VMS1100 about a year ago.&nbsp; Back then it was recommended to go into user settings and set HDMI output to L-PCM as a workaround.&nbsp; I also read that there was an update at that time that was going to fix the issue.&nbsp; That thread seemed to die out in activity around that time so assuming that maybe an update was received to fix that issue on the VMS1100.&nbsp; So now that I have the VMS4100 I am experiencing the same A/V sync issues that others reported in the past.&nbsp; &nbsp;I tried the same workaround and it seems to have worked. I used an old remote and pressed the green D button for 10 seconds to get into user settings and set HDMI output to L-PCM. There is not much info yet on the new voice remotes with the VMS4100 but I found that you can get into user settings by pressing the power button and then the OK button twice. This will put you in diagnostics but then press the left arrow button to get to the main menu to select user settings. When pressing power off it may also turn off your TV so prior to doing this point the remote to a different area away from the TV so it does not turn off the TV and just the VMS4100 gets turned off, then press OK twice as described above.</P><P>&nbsp;</P><P>I wanted to start this thread to help others since the VMS4100 is so new and to let it be known that these boxes are having the same issue reported over the years with other prior STB's. I want to make it known to Verizon so that hopefully there will be a fix for this and the workaround will not be necessary.&nbsp; My VMS4100 is at release APR6.0, Build Number 22.45.</P>Sat, 26 Jan 2019 23:06:19 GMThttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/877379#M66817mitch0532019-01-26T23:06:19ZRe: FIOS TV One VMS4100 A/V Sync Issueshttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/878878#M67100
<P><SPAN>I also recently upgraded to FIOS TV One which includes the VMS4100 media server and 2 clients.&nbsp; I have the VMS4100 attached to a Samsung NU8000 and a Barska Audio TR-200 Sound-Deck connected TV-&gt;sound bar with an optical cable.&nbsp; To get any sound at all, I had to set the TV to PCM.&nbsp; No sound isn't quite the sync issue you have over HDMI but thought maybe the TV audio setting had to match PCM.&nbsp;&nbsp;</SPAN></P><P>I still have an issue controling the volume through the STB.&nbsp; I was able to do that with the VMS1100, set the volume control to Variable, but that doesn't work for me on the VMS4100.&nbsp;</P><P>I'm sure by now you've worked through all of the setup options with the receiver in-line or direct through the setup of the remote.

<P>I'm having this issue and just signed up for Fios. I've tried all the ideas and spent time with support. Support continues to tell me to restart my box. That doesn't work. Does anyone have any other suggestions? I'm thinking of canceling my account and switching to xfinity.</P>Thu, 05 Sep 2019 09:37:37 GMThttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/885185#M68484TomM7112019-09-05T09:37:37ZRe: FIOS TV One VMS4100 A/V Sync Issueshttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/885219#M68495
<P>Which issue are you having? No sound or sync issues? If no sound I assume you tried setting sound to L-PCM in the service menu, if sync, while there did you notice the additional HDMI setting option? If you select that you'll see a lip sync option, probably set to auto. Change it to 150, and see what happens. If audio is still ahead of video increase the value, if audio is now behind video decrease the value.</P>Fri, 06 Sep 2019 03:31:31 GMThttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/885219#M68495clem532019-09-06T03:31:31ZRe: FIOS TV One VMS4100 A/V Sync Issueshttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/890567#M69691

<P>I just struggled through a similar situation in which my sound bar was not syncing with sound. &nbsp;I tried a number of things...but through this thread I came across the info and tried the auto delay to manual and 150...didn’t work very well... but noticed there was also a setting to turn auto delay “off”...I did that and now sound seems to be syncing fine. &nbsp;Fingers crossed that continues and solved the problem. &nbsp;Thanks&nbsp;</P>Sun, 05 Jan 2020 21:13:51 GMThttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/890624#M69699FriscoKit2020-01-05T21:13:51ZRe: FIOS TV One VMS4100 A/V Sync Issueshttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/891140#M69793

<P>Instead of going to LPCM,&nbsp; did you try setting a fixed delay, like 150 or more In the service menu under advanced HDMI options? You could also try turning audio delay off there too and let your other equipment do any compensation. Do you see a lipsync&nbsp; issue if you go direct from the box to the tv? Also did you try game mode on your TV settings to see if the lag is being caused by some video processing the TV is doing? There is also supposed to be a new firmware update being pushed out for the 4100 that includes audio and video passthrough. That might also be the solution. Dont be so sure switching providers will be the cure.</P>Fri, 17 Jan 2020 13:17:57 GMThttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/891149#M69794clem532020-01-17T13:17:57ZRe: FIOS TV One VMS4100 A/V Sync Issueshttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/891184#M69800

<P>Try fios box to soundbar via HDMI,&nbsp; soundbar to TV via HDMI ARC. Did you try optical from fios box to soundbar? What you are describing is a VIDEO lag, not audio. The screen image is behind the audio. Try setting your TV to game mode and see if it improves. If it does there is a setting in the TV menu that is causing excessive image processing and delays the video with respect to the audio output. Also look at audio delay options in the TV menu, or sync options, and in any menu in the soundbar. I still think you should be able to get this acceptable through the delay setting in the Fios service menu.</P>Sat, 25 Jan 2020 04:30:43 GMThttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/891517#M69926clem532020-01-25T04:30:43ZRe: FIOS TV One VMS4100 A/V Sync Issueshttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/891823#M70022
<P>I don't understand why it's marked as SOLVED. The "solution" reply is irrelevant, the OP is talking about an audio lag and not a video lag. There is indeed an audio lag from the Fios TV boxes when outputting in DD format. It should be solved by a firmware update or box replace by Verizon.</P>Fri, 31 Jan 2020 15:29:17 GMThttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/891823#M70022Mbpe3002020-01-31T15:29:17ZRe: FIOS TV One VMS4100 A/V Sync Issueshttps://forums.verizon.com/t5/Fios-TV-Technical-Assistance/FIOS-TV-One-VMS4100-A-V-Sync-Issues/m-p/891826#M70024
